IMPROVEMENT IN DRAWING-FRAMES.

Specification forming part of Letters Patent No. 222,540, dated Deccniberfi, 1879; application filed September 26, 1879.

To all whom it may concern:

' Be it known that I, JAMES SMITH, of New "Albany,in the county of Floyd, and in the State a of Indiana, have invented certain new and useful Improvements in Drawing-Frames andI dohereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, an d to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a stop-motion for drawing-frames, as will be hereinafter [more fully set forth.-

In the annexed drawings, Figure 1 is a side elevation, and Fig. 2 a plan view, of my invention. Fig. 3 is a detailed perspective view of a part thereof.

A is the trumpet; B, trumpet-support; G

C,calender-1'ollers, and D roller-support. a is fulcrum-pin; E, the foot. bis regulating- When from any cause whatever the sliver is not thick enough and the friction is thus decreased, the weight F, not beingv balanced,

causes the rod d to fall, and the catchG, being attached to said rod, falls also. The wing I, coming around, is caught by the catch G and stopped, thus causing the machine to stop.

When from any cause the sliver is too thick,

or the trumpet is choked by a large lump or bunch, the trumpet is pulled downward, causing the rod d to rise, and the catch H is pulled up from its normal position, and the wing I, coming around, is stopped by the catch H, and the machine is stopped.

If the lump is short and small, it goes through the trumpet so quickly that the catch His apt to rise slightly and fall again before the wing I can come in contact with it but this is remedied by'the holder J, for, even if the catch H is raised but slightly, the holder will push it within the circle of the wing and hold it there until the wing comes in contact with it, and the machine is thus stopped. The attendant can tell which can contains the lump by seeing the holder J outof its normal position.

The size of lump required to stop the machine may be regulated to suit by weights on the wire 1', from one grain upward.

Having thus fully described my invention, what I- claim as new, and desire to secure by Letters Patent, is-'- 1. In a drawing-frame, the combination of the trumpet A, foot E, adjustable rod 01, connected to the foot, and provided with the adjustable weight F, the pivoted catches. G H, connected together by the link f, and the rod 6, connecting the catch G to the rod (1, all constructed and arranged to operate substantially as and for the purposes herein set forth.

2. The catch-holder J, in combination with the catch H, for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 18th day of July, 1879.
